Amplifier Current Draw—120 VAC
"Current draw" is the amount of AC current an amplifier demands while it is operating.
Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full
power, and full power, with all channels driven simultaneously. The figures shown on this sheet are
for 120 VAC usage; for 230- and 100-volt operation, see the companion sheets. For typical usage,
use the idle and 1/8 power figures.

1/8 Power
Current draw at 1/8 of full power is measured
with pink noise as a signal. It approximates
operating with music or voice with light clipping
and repesents the amplifier's typical "clean"
maximum level, without audible clipping. Use
these figures for typical maximum level
operation.

Where an asterisk (*) appears, the data was not available at press time. The designations "na" and
"nr" respectively mean "not applicable" to the particular amplifier model and "not rated" for the
particular load impedance. Bridged mono into 8 ohms is equivalent to 4 ohms per channel; into 4
ohms is equivalent to 2 ohms per channel.
1/3 Power
Current draw at 1/3 of full power is measured
with pink noise as a signal. It approximates
operating with music or voice with very heavy
clipping and a very compressed dynamic range.
Full Power
Current draw at full power is measured with a 1
kHz sine wave. However, it does not represent
any real-world operating condition.
